An adjustable, removable seat structure,

in accordance with this invention and for" use in connectionwith structural iron work, comprisesa combined supporting and carry the other ing section or element, hereinafter termed e lement,"a supporting section, setof hold fast devices, and retaining devices.

The combined supporting and carrying I element is referred to generally by the refer-i ence character 7 and which comprises a rectangular body portion8 provided at its ends with a pair of rightangularly disposed extensions 9, 10 arranged in superposedrela tion. Formed integral with one side edge" of the body portion 8 and of a widthless thanthe height'of the latter, 'as well as po- I sitioned equidistant from each end or said body portion 8, is a coupling wing 11 bent to oppose that face of the'body portion 8 op 'aosite-that-face from which the extensions 9, 10'project. v The clamping wing 11- is of a length tofextend transverselyof and substantially across the body portion 8. The

wing 11 includes a curved portion 12 which merges into the body portion '8 and said wing 11 further includes a portion 13 'wl'1'i'ch op poses, but is spaced. from, the body-portion 8 and is formed with a pairof openings 14', 15 each arranged adjacent the side edge of the part 13 and positionedin proximity tothe end edge of the, wing 11.: The walls of the openings {14, '15 are threaded The erten'sion 9,,as well as the extension, 10 is of rectangular contour, and extending tively positioned in one of lengthwise of said extensions are slots 16 having their ends arranged in close proxim ity to the end edges of the extensions. Selecthe slots 16 is a retaining device consisting of a short headed bolt 17 provided with a securing nut 18. The head of the bolt 17 is seated upon the outer side face of the extension.

The supporting section is referred to generally by the reference character 19 and it consists of a rectangular body portion 20 of greater length than the body portion 8. The bodyportion 20 tern'iinates at its upper end in a right-angularly disposed rectangular extension 21 provided with a slot 22 adjacent each end edge thereof. In proximity to each side edge of the body portion 20 there arranged a lengthwise extending slot 23. The slots 22 are of less length than the slots 16 and the slots 23 are of greater length than the slots 16 and 22. Selectively mounted in one of the slots 22 is a retaining device consisting of a headed bolt 2% provided with a securing nut 25. The head of the belt at seats upon the upper face of the xtension 21.

Selectively mounted in one of the slots 23 is a set of holdfast devices and each of which consists of a cylindrical bar of appropriate length and which is indicated at 253. The bar 26 is peripherally threaded from end to end. Integral with the outer end of the bar 253 is a head 27, and threadably engaging with the bar 26 is a clamping nut 28. The holdfast devices coact with the threaded walls of the openings 1 formed in the wing 11 and abut against an upright to provide for the clamping of the combined supporting and coupling sections in stationary position. The nuts 28 of the holdfast devices abut against that face of the body portion from which the extensions 21 project. The extensions 9., 10 and 21 provide seats or supports for the cross members for positioning them relative to an upright so said cross members can be welded to the upright and after the welding or connecting operation the seat structure is removed so it can be employed again.

A flanged column or upright is indicated at 29 and in Fig. 1 the cross members 30, 31 and 32 in the form of I-beams are illustrated as supported in position with respect to the column 29 by a pair of adjustable, removable seats in accordance with this invention. The cross member 31 is of less height than the cross members 30, 32. The cross members 30, 32 are mounted on the extensions 9 of a pair of combined supporting and coupling elements and the cross members 31 are mounted on the extensions 21 of a pair of supporting sections. The retaining devices carried by the flanges 9 abut against the edges of the lower flanges of the crossmembers 32 and'there'taining devicesjcarried by the extensions 21 abut against the edges of the lower flange of the cross member 31. The supporting sections 19 have been vertically adjusted in a manner so as to position the base flange of the cross members 31 above the base flange of the cross members 30, 32, but with the top flange of the cross members 31 flush with respect to the top flanges of the cross members 30, 32.

With reference to Fig. 2 the cross members 3 1-, 35 and 36, in the form of Lbeams are illustrated in position with respect to the column 29 and are supported in such position by the pair of seat structures in accordance with this invention. supported by the extensions 21. The cross member 36 is supported by the extensions 21 and the cross member 35 is supported by the extensions 9. i v

With reference to Fig. 3 the column or upright is also indicated at 29 and the cross members at 34, 35 and 36', andFig. 3 is a base plan of the arrangement shown in Fig. 2;

it but one cross member is tobe connected in position pair of seat structures are to be employed. If two or more cross members are to be supported in position relative to the column29, four or six seat structures are to be employed.

lhe combined supporting and carrying element is clampedto a flange of the column 29 by the holdfast devices which extend through a slot 23' .and openings lei, 15. The supporting structure 19 is vertically adjustable relative to the element 7 more adjustable inwardly and outwardly with respect to said element 7. The inward and outward adjustments of the section 19 is provided for by the pair of slots 23, in

connection with the set ofholdfast'jdevices which extend through the openings 14, 15 of the element 7. The retaining devices act as means for centering the cross members as said devices are adjustable in the slots 16 and 22. After the seat structure has been clamped in supporting position to the column 29 and performed its function in-supporting the cross member the said structure can be expeditiously removed from the column 29 by loosening the set of holdfastv devices which are employed for detachably clamping it in position. The retaining devices are arranged to engage the edges of the ba e flanges of the cross members. The extensions 16 provide means for supporting cross members extending at right angles with respect to the cross members supported by the extensions 21. The'providing of the body portion 7 with an upper and a. lower extension, or the extensions 9 and 10, permits of the elements 7 to be employed from either side of the column 29. 1

The combined supporting and carrying elements 7 are adapted toebe coupled against the flanges of the column 29 and project out- The cross member 3 is.

and is furthery when said structures 19 are coupled tothe elements 7. As the structures 19 have the body portions 20 thereof, when connected to the inclined coupling wings, 11 abut said wings, the said structures 19 are disposed at an angle with respect to the elements 7. As

shown in Fig. 3 the supporting structures 19 are disposed at opposite inclinations with respect to each other. 1

It is thought the" many advantages'ofan adj ustable, removable seat structure, in accordance with this invention for the purposeset forth, can bereadily understood, but although the preferred embodiment of the invention is as illustrated and described, yet it is to be understood that changes in the details of construction can be had which will fall'with in the scope ofthe invention as claimed.
